2 Claims.

This invention relates to radio constructions, and more particularly tomodes of inserting the radio chassis in the radio cabinet.

One object of this invention is to provide an improved radioconstruction in which the radio chassis is inserted into the bottom ofthe radio and secured therein.

With the above and other objects in view, this invention includes allimprovements over the prior art which are disclosed in this application.

In the accompanying drawings, in which one way of carrying out theinvention is shown for illustrative purposes:

Fig. 1 is a perspective view of a radiol constructed in accordance withthis invention;

Fig. 2 is a bottom perspective view of the radio cabinet in upside-downposition and prior to the insertion of the radio chassis therein;

Fig. 3 is a bottom plan View of the radio cabinet with the radio chassissecured therein;

Fig. 4 is a sectional view on line 4-4 of Fig. 3;

Fig. 5 is a sectional view on line 5-5 of Fig. 3; and

Fig. 6 is a perspective view of the support or base-plate.

In the description and claims, the various parts are identied byspecific names for convenience, but they are intended to be as genericin their application as the prior art will permit.

Referring to the drawings, the radio cabinet or case I0 consists of atop II and a body I2 that is continuous and in the form of a flattenedellipse, and a support or base or bottom-plate I3, the latter beingdetachable.

Inside the cabinet I0, adjacent the opposite bottom ends of the cabinet,are secured two brackets I 4. Each bracket has a curved face I5 shapedto fit the inside curved surface I6 of the case, and a curved bead I1projecting from the face I5 and fitting in a curved slot I8 in the innerface I6. Each bracket I4 is formed of wood and is glued in place andglued upon the wooden blocks I9, which latter also are glued to theinner surface I6 of the cabinet I 9. Bolts 20 have heads 2| engagedagainst the undereface 22 of the bracket I4 and extend up through thebracket, and are secured firmly thereto by the nuts 23 with the freethreaded ends 24 of the bolts extending up through and beyond the largebottom opening 25 of the cabinet III. The cabinet IIJ also hasshaft-holes or openings 26.

The radio chassis 21 includes a box 28 formed of two sheet-metal parts29 and 30, the part 29 being integral with the projection or flange 3l,and the part 30 being integral with the projection (Cl. S12-7) or ilange32, at each end of the radio chassis. The box 28 has certain radioIparts (not shown) secured in the interior thereof, and other radio parts(not shown) secured to and extending below the bottom 33. The flanges 3Iand 32 have elongated slots 34 therethrough. Each pair of flanges 3 I,32 are secured together by any suitable means such, for example, as bythe bolt-member 35.

In, assembling the chassis in the cabinet, the cabinet is placed inupside-down position, such as shown in Fig. 2, and the chassis islowered into the cabinet as shown in Figs. 3, 4 and 5, to bring theslots 34 over the bolt-ends 24, with the rear face of the chassisoccupying some such position as indicated by the broken line 36 (Fig.3), and with the shafts 31 having their extreme forward ends indicatedin broken lines at 38, spaced somewhat back away from the inside frontface 39 of the cabinet to provide suitable' clearance for the chassis asit is lowered into the cabinet. The chassis is then slid forward withthe flange 3|, 32 moving along the brackets I4, to project the shafts 31the desired distance through the shaftopenings 26 in the front of thecabinet.

Washers 4I and nuts 42 are applied to the threaded bolt-ends 24 and Woodscrews 46 are screwed through the flanges 3I and 32 into the woodbrackets I4, to firmly secure the flanges of the chassis to thebrackets. 'I'he base -or bottom-plate I3 is then inserted in thebase-opening 25 of the cabinet, with the threaded bolt-ends 24 extendingup through the holes 43 in the base I3. Lock-washers 44 and nuts 45 arethen applied to the bolt-ends 24 to securely attach the base I3 inplace, whereupon the assembled radio may be inverted to its normalposition shown in Fig. 1. Suitable knobs, such as indicated in brokenlines at 40, may be applied to the ends of shafts 31 for operating theradio.

The invention may be carried out in other specific ways than that hereinset forth without departing from the spirit and essentialcharacteristics of the invention, and the present embodiment istherefore to be considered in all respects as illustrative and notrestrictive, and all changes coming within the meaning and equivalencyrange of the appended claims are intended to be embraced therein.

I claim:

1. A radio construction comprising: a hollow radio cabinet havingnon-separable top, front, end and rear Walls and shaft-openings in itsfront wall and the bottom being open and supporting-brackets on theinside of the opposite end walls of the cabinet adjacent the bottomthereof; and a radio chassis having shafts projecting from its front andinsertable into said cabinet through said open bottom and adapted topass between said brackets and having flanges engageable against saidbrackets and slidable transversely of said insertion movement to projectsaid shafts through said shaft-openings and said flanges being adaptedto be secured to said brackets.

2. A radio construction comprising: a hollow radio cabinet havingnon-separable top, front, end and rear walls and shaft openings in itsfront wall and the bottom being open; supportingbrackets on the insideof the opposite end walls of the cabinet adjacent the bottom thereof;bolts secured to said brackets and having threaded ends extending fromsaid brackets toward the plane of the bottom edge of the cabinet; aradio chassis having shafts projecting from its front and insertableinto said cabinet through said open bottom and adapted to pass betweensaid brackets and having flanges engageable with said brackets, and saidchassis movable transversely of said insertion movement to project saidshafts through said shaft-openings; a base-plate engageable over saidopen bottom and over said bolts; and means threaded on said bolts andsecuring said flanges and said base-plate to said brackets.

OS'I'ILIO CICCARELLI.
